Whoa! This was really interesting and pretty awesome! Keep up with the wicked content and experiments guys!
Very glad you guys teach people proper disposal. W2B!
I like sci guys too much because they always reply to peoples comment.
I am very much impressed .
:)
I wanted videos on the theories which i have read in the books.
And this channel has given the best and neat explanation .
Aman Rubey We're glad you like our videos. If there are any theories or concepts you want us to cover please let us know.
Great info and well presented. Thank you!
The Sodium Hydroxide that you created could be used to create soap. But that's another show! Though you would have wanted to use the Graphite to create it, so you would have had the precipitate to deal with.
Have a better day!
Oh my Gosh! Thank you for this breakdown!
Perfect for our homeschool unit. Thank you!
wish i had seen this before submitting my chem assignment - i completely missed the sodiumhydroxide bit of electrolysis... uh oh
Well done! Informative and fun too.
We are glad you loved it. I hope you will subscribe and share these with your friends :D
It really depends on what the something is. Electrolytic cleaning works for salt deposits because salt ionizes very easily. I don't think it would necessarily work on something sticky like gum to instance.
the water changed color because the chloride reacted with the metal and did not become a gas. that is why you only had bubbles on one spoon.
Silvan Geissmann means oxygen is not present?
@@RUTV-et8ww Yes , neither is chlorine .
Silvan Giessman I agree with you. Do you think lye is formed? I don't know for sure
It reacted with the metal to form what exactly?
Will the reaction going on in the beaker be different from when a u- tube is used?
wow! Awesome explaination of the chemical equation and the rest! Definetly u gave a much more better and clear explanation than my chemistry teacher😅
Tirtha Bandi yip
no chlorine gas is release out of the solution, once produced it immediatly transformed into hypochlorite ions (bleach)...
@@francoiszaviska4064 are you mad
It is really fun and looks really cool as well. - Ryan
Hi I wanted to know why one side does makes bubbles and the other doesn't can you help me?
Great video! Can you guys explain how electrolysis is used to create Kangen Water ? Thank you!
Amazing Video and explanation
Because of u guys I got first place at my science fair competition
Wherefore art thou, sci guys? Come back!
Great job sci guys!
Loved it!
great job :) I look forward to more
Currently using for homework. Very informative and helpful!😊
Muy interesante la explicación.
You guys are the best at science!
Will the H and Cl ions combine to HCl when collected in a jar.
I have a question for you. Which reaction occurs in the cathode and is this side connected to the positive or negative end of your battery?
This is awesome.
When you put rusty objects in vinagre, you also get H2? Or/and something else?
this is so cool :') I wish childhood me discovered this channel
Well done guys!!
great video guys, thankyou for it, can you tell me if you are still doing videos?, and if so, could you do one with electrocoagulation?
I have a feeling I'll love these a lot. Subbed!
I'm currently learning Physical Science, also planning on working on getting a degree in science soon, and I'm sure these will serve as a nice introduction to the subject~
Enjoying it so far~!
Lexyvil Thanks!! it's great to hear that you find value in our videos. Good luck with you degree!!
Did you end up getting your degree? Your comment was 7 year's ago, so I was just wondering. 🙂
@@scootermom1791 Yeah, and now I'm into Computer Systems Engineering in Uni. So that's still some 2 long years left lol.
@@Lexyvil Awesome! I always wonder where life takes people. Good that you were able to follow your goals! 🙂
How's it going?
so awesome and so cool!!!!!
Awesome video!
Very nice, well explained
can u give me the relationship between voltage current and amount of hydrogen gas produced and also relationship between electrical energy consumption
if the spoons were stainless steel without coating, would the steel react at all with the NaCl?
I want to have a 22 inch line of platinum to produce hydrogen bubbles(cathode)-- I think the gauge of my wire is probably a bit smaller than 20 gauge. I don't have a lot of platinum, so I want the bulk of the wire to act as the cathode. What is the minimum length of platinum wire that I need to act as the anode in order to have my 22 in length of cathode produce hydrogen bubbles evenly?
Thanks!
This is so helpful!!! am skeptical then abt the commercialize Hypochlorite generator, now popular, force of nature. Now i can understd the Chemistry abt it . Hope you can help us make a good formula for the vinegar salt ratio to make a DIY hypocrite. plssss
I have a question. there will be a product of sodium hydroxide aka lye in the electrolysis of salt water but what would happen if you use the sodium hydroxide solution produced earlier for electrolysis? and what would be the products if you use that sodium hydroxide?
This is the first video I've seen from you guys and I'm already hooked and subscribed! Hope you guys get even more subscribers as time goes by. You deserve them.
Jared Swapp Thanks :) We appreciate the words of encouragement :)
how does increasing the temperature of the solution affect the rate of formation of hydrogen and chlorine at the cathode?
What is the use of membrane in electrolysis ? Is it necessary to use a membrane in electrolysis of water+koh solution ? I'm using a dry cell hho generator.. plz help.
Great video thanks for sharing this knowledge. Is this the same process which is used by pool chlorination devices?
Bilal Baig From what we understand pools are generally treated with chemical chlorine in a controlled liquid format. I don't think they use electrolysis to do this.
why did you use NaCl to increase water's conductivity? what else can be used? what is best substance ?
Thank you sir i understand very well wow
What metal is the most efficient for electrolysis?
Thanks you helped me in my science project thanks again😊😊
What can you do with the lye? Could it be like a drain cleaner?.
Thank u so much u helped me do my science fair projet
can i do this in open circuit? like a wire connected to the wall then I run it on the water?
Hi. Can you confirm that the sodium ion would accumulate on the cathode. Would this have been more apparent if the experiment had run for longer? Thanks.
Yoo guys, do you have any idea about the efficiency rate of the reaction, if you look at the production of hydrogen gas alone?
why when disposing of the lye a strong base do we use vinegar a weak acid?
you are like amazing .sci guys u helped me a lot as I had to make a working model on electrolysis and was unable to do so you are such a saviours thank you a lot and you made my interest in chemistry thanks...............
aditi sharma You're most welcome :) We are glad that we could help.
A way you can test to see if it was from the wires would be to attach the wires to graphite leads and then do the experiment. Graphite should not react with the water. If this removed the green colour then you know it was from the corrosion of the wires. If the green colour is till there, I would suggest to change the container to a glass one and try again. We noticed that our solution changed to a green colour over time, after we let it sit and the colour accumulated into a precipitate.
graphite ,is it a positive charged ion or negative ?
Nice One . . . Thanks . . .
how would you get oxygen instead of chlorine? what would you change NaCl to?
Great video guys. I have a couple of questions. Is the O 2 produced at the end breathable? Would their be a way that the chemical reaction go off instantly or it’s always going to take time to get a fully separation of molecules??
Thank You
SAFETY NUMBER 1
Wow , this video had awesome explanation .
I want to know calories produced by 1lg solution will be harmful or not
Can I use a 1.5 V AA battery for this experiment (by putting the + and - terminals in between the 2 spoons)? Will it still work? Thanks!
May I use this techniques for my presentation??
Thanks guys you helped me in my science fair project
Azozgaming I'm doing the same thing!
Lol
Are there any uses around the house, for the water left over after electrolysis rust removal? Would it beneficial to the soil if I we’re to water with it for example. I have a bit of a hobby renovating BBQs with cast iron grates, and more often than not friends want me to help with their neglected BBQs; and as part of the process I use electrolysis to get rid of the rust. I utilize plain tap water with soda ash Na2CO3 which I make at home from NaHCO3. I strictly keep in mind not to use this rust removal method for anything that is made of stainless steel, mainly cuz of the chromium in it. Anyway, I see it as such a waste to neutralize this water and just dump it down the drain, that more often than not I’ve wondered if I could use it to water the plants, shrubs, lawn, and flowers around the house? I haven’t done it, mainly because I don’t want to experiment and kill sections of the lawn or plant to find out what someone else might know already. Yes, my water has the typical leftover crud in it, when done with the rust removal by electrolysis. What do you science guys think? Perhaps there’s even a use for the left over liquor without neutralizing it..... not really sure.
can you tell for tio2 water splitting we need -1.23 V why and how one can get?
Can i use 220v ac and convert into dc with diode and stainless steel sheets as electrode .will it work and can i generate a lot of hydrogen?
Please make video on electrolysis of concentrated back using the graphite electrode. Please response what are the product form at the end.
How would you dispose it if you are using a hoffman voltameter
Hello I got myself the same reaction you also got but the thing is dose hydrgoen burn green?
Does the electrolized water can be use as a cleaning agent?
can you explain orp and how orp relates to pH as well as to killing of microbes? they sell these commercial water electrolysis units with pH from 2-11 as well as +orp to -orp mV and i want to understand what it means. i heard it has to be up to 650 mV orp to kill microbes of health/food safety concern (is this true? e coli, salmonella, listeria, ?amoebas, etc.) but i don't know if this is orp in positive or negative mV.
Wonder if this can be used to unclog a drain. Instead of buying lye in the form of a drain cleaner granules.
good day brows thats experement are example to use us tigwelding alternate of argon gas?
At the beginning you said that Electrolysis "Adding energy in the form of electricity to a compound to break its chemical bond returning it into its basic components", but then it was never explained how it returns into its basic components. For example a Salt Water pool uses Electrolysis, if the salt is continuously transformed into chlorine and hydrogen, why is it that you don't need to add salt to the pool other than at the beginning of the season? Would be able to explain? Thanks
When i was around 10 year old .. i trying to boil water using 12v battery and 2 saving blades .. when 1 start the experiment i found hai same colour of solution like (brown or a green) but I can't understand what happened.. why this water change it's colour .... But after a long period of time 1 found all my answers ... Thanks dude 😊👍🏻👍🏻
What happened? I did the same but there's some insoluble green solid and it turned brown in the air.
in an HHO generator, oxygen is released with hydrogen right? Why does oxygen stay in the water as sodium hydroxide?
Owesome guys
Is the salt NaCl you used in your experiment in the daily eating salt?
what if we use Fe as the electrode with CaSO4
i did this with kosher salt used carbon rods as electrodes and 2 9v batteries it started good but the a cloudy liquid formed at the bottom what is this i did use a clean beaker
Question: I'm now conducting an experiment that studies exactaly what concentration of NaCl will cause the production of chlorine gas. I used graphene electrode in order to avoid unknown products. However, the cathode starts producing greenish precipitate after the NaCl concentration exceeds 3M. I'm wondering if that's related to chlorine gas, but I get pretty confused, becuase 1. chlorine gas should be produced in the form of GAS not precipitate 2. Chlorine gas should be produced at the anode.
Please help me out! Thanks guys!
Hello .
Is it possible to have hydrogen (electrolysis) from salt/sea water
(Only generally speaking)
under following conditions :
Input voltage 5 Volts DC Voltage.
Total resistance between electrodes in the sea salt water 0.1 Ohm
Important : There is resistor connected in series with resistance R = 4 Ohm.
So total resistance of the entire circuit is 4.1 Ohm.
The question is only general.
Really thank you a lot .
BR.
Stoyan.
I'm assuming the spoons are stainless steel?
If so, the oxide might be a chromium compound of some sort
Yeah, I was just thinking that. Using stainless steel as your electrodes is *super* dangerous. Rebar's a much better option (though harder to do with a 9v battery).
I think the magic word is carcinogens . . . . .
is it possible to use baking soda to be the electrolyte ???
( i think it may be a bit safer.....)
We have a few questions. Does your solution still contain NaCl? How did you send the charge to the solution? (Metal wire) Finally was the power board direct or alternating current? This will tell us if any compounds were isolated on ether side during the reaction. The white precipitate could be hard water residue if you cooked off a lot of the water. If you used a metal wire the discoloration could be from the metal oxidizing during the reaction. With more info we can help further.
Probably a little NaCl left. But not much as black as it was. No, they sent the charge from the 9v battery directly to the spoons! What are you talking about..power board. The battery is DC. This is just from my observation.
Hi, thx for the video. It would be great to hear you make a hypochlorous acid making video as a disinfectant for the ongoing pandemic.
I was just thinking the same! There’s a product that showed up on my Facebook and I watched this video. I’m trying to figure out what the difference is. I could make my own!
@@elisasosa6241 it's been 10 months since I wrote this comment. Now, you can find a video in my account (unfortutanetely in Turkish). Maybe it helps :)
Does this solution negatively affect a septic system?
do you even need to add salt if you use a graphite pencil and does the graphite also cause a catalyst effect lowering the amount of energy for the reaction to proceed?
How come some Electrolysis processes make sodium hypochlorite and other make HOCL. If I add vinegar to the salt and water does it produce HOCl and without the vinegar you get sodium hypochlorite?
Agreed!
this will help me with my gcse chemistry exam
CfCFan99 yay!!
Can anyone explain the chemistry of making hypochlorous acid? I’ve seen a few attempts, but nothing convincing. If vinegar is in the mixture, is the gas given off carbon dioxide? Or is it still hydrogen, as it would be without the vinegar?
Hey Sci Guys, love the vid. Two questions: first, what do we change so that we get oxygen being produced on one spoon and hydrogen being produced on the other? Second, if we replace the spoons with strips of aluminum or nickel, will we still get a precipitate? Thanks in advance.
the Ox comes off the Pos. plate H comes off the neg. other metals go away to fast but using 316-L stainless steel, that wont discolor your water either, and you really only need 2 tbl spoons of sodium hydroxide per Qt. for those trying to make HHO, if you use 12 volts you can put 5 Null plates between the Pos and Neg being about 2 to 3 volts per plate
from your experiment, does it mean the electrodes you used most have been decomposed?
Can tge beaker and spoons after electrolysis be used again for eating and drinking purposes???
Plz Sir, answer this...
If I buy an H2oe3 cleaner from the adverts should I wear PPE clothing? They don't mention it on the adverts. Or is that why you add vinegar?
Does both the gases nitrogen and chlorine are separately released by both the spoons??
Superb.....Actually i am interested about Electrolysis of water...but here i just want to know how i can make Eo water
Bro, could you do a video on electroplating please and awesome video by the way
Damien Martin That sounds like a great idea. I will look into if we will do an experiment or if we do a lecture about electroplating. I cannot promise when it will come out but we will try and do it sooner than later.
